KYW 825"   If officer is under a DUI TIPS code, then dispatcher may not call back to check as to not interfere with field sobriety testing.

Mobile Extenders  (this is the California Highway Patrol version, may be about the same?)
   F1: 155.505  with the primary tone.  (NOTE 1)
   F2: 155.505 1st alternate tone
   F3: 155.505 2nd alternate tone
   F4: ?
   F5: ?
   F6: ?
   F7: 155.475 ?
Note 1: With the old hand-helds there was no way that two units from different areas (i.e. different dispatch frequencies) could have their extenders operational at an out-of-vehicle scene -- when an officer transmitted, both mobiles would be brought up.   The receiver of the extender has an attenuator making a low wattage HT usable for only a short distance (typically less than 50yds).  To make sure  there is only one extender being used within close proximity each vehicle extender sends a short burst tone to see if others are active.  If it is within range of another active extender it doesn't turn on at all.   The HT is then using the other vehicle radio (the one that was already turned on).

Now for the PL explanation.  There are three channels on CHP HT's that relate directly to the extender.  Channel 1 (also called PP or Person to Person) does not transmit any tone nor does it decode.  It is meant for HT  to HT use.  Channel 2 has a subaudible tone on transmit allowing the officer to talk to dispatch. (ie, transmits on the input freq of the lowband radio)  Channel 3 has a different subaudible tone on transmit allowing the officer  to talk to other officers. (ie, transmits on the output of the lowband radio) All channels are carrier squelch on the receive so that PP can be heard regardless of other traffic.

Here are the new  frequencies.
 
No PL and analog only operations are allowed on the Calling Channels while the PL of 156.7 Hz. (5A) is allowed under certain circumstances 
on the Operations channels. Also, digital operations are allowed on the Operations Channels after 2004 under certain circumstances.
 
IEMA controls these frequencies in Illinois. They will be authorized for use in multi-agency situations only, not as intra-agency 
communications channels. The VHF channels are simplex only while low power temporary repeaters may be authorized on the UHF channels. 
Simplex on the 453 side of the UHF is allowed and encouraged. 

Other channels in the master plan include:
IREACH   155.0550
ESMARN   155.0250
ISPERN   155.4750
IFERN    154.2650
IFERN2   154.3025
RED FG   153.8300
WHITE FG 154.2800

GOLD FG  153.8375
BLACK FG 154.2725
GRAY FG  154.2875
GREEN FG 150.7900 (Informal)  No PL is to be used on any of these channels.

Also to be considered are the ITAC channels. Although they do not appear in the IEMA plan they are set up in a similar way. All the 
below use a PL of 156.7 Hz nationwide and are controlled by the state designated law enforcement agency in each state. In Illinois the 
control agency is the ISP.
